1 INCONEL nickel-chromium-iron alloy 601 (UNS N06601/W.Nr ) is a general-purpose engineering material for applications that require resistance to heat and corrosion. An outstanding characteristic of INCONEL alloy 601 is its resistance to hightemperature oxidation. The alloy also has good resistance to aqueous corrosion, has high mechanical strength, and is readily formed, machined and welded. The limiting chemical composition of INCONEL alloy 601 is listed in Table 1. The composition is a facecentered-cubic solid solution with a high degree of metallurgical stability. The alloy's nickel base, in conjunction with substantial chromium content, provides resistance to many corrosive media and hightemperature environments. Oxidation resistance is further enhanced by the aluminum content. The properties of INCONEL alloy 601 make it a material of broad utility in such fields as thermal processing, chemical processing, pollution control, aerospace, and power generation. Alloy 601 is a standard material of construction for various types of thermal-processing equipment. Industrial-heating applications include baskets, trays, and fixtures for annealing, carburizing, carbonitriding, nitriding and other heat-treating operations. In industrial furnaces, the alloy is used for radiant tubes, muffles, retorts, flame shields, strand-annealing tubes, woven-wire conveyor belts, chain curtains, burner nozzles, and electrical resistance heating elements. Other thermal-processing applications are thermocouple protection tubes, furnace-atmosphere generators, and infrared radiant screens. Chemical-processing applications for alloy 601 include process heaters, condenser tubes in sour-water strippers, and insulating cans in ammonia reformers. The alloy is also used for combustor components and catalyst grid supports in equipment for nitric acid production. In petrochemical processing, the alloy is used for catalyst regenerators and air preheaters in the manufacture of high-density polyethylene. In pollution-control applications, INCONEL alloy 601 is used for thermal reactors in exhaust systems of gasoline engines and for combustion chambers in solidwaste incinerators. In the power-generation field, alloy 601 is used for superheater tube supports, grid barriers, and ashhandling systems. The alloy is also used for jet-engine igniters and for combustion-can liners, diffuser assembles, and containment rings in gas turbines for aircraft, industrial, and vehicular applications.

2 Table 3 - Thermal Properties of INCONEL alloy 601 Mechanical Properties INCONEL alloy 601 has good mechanical strength. Nominal mechanical-property ranges for various products are shown in Table 5. As indicated by those values, the strength level exhibited by the alloy varies with the form and condition of the material. The optimum condition for alloy 601 depends on the type of application and the service temperature involved. In general, the solution-treated condition is used for rupture-limited applications (temperatures of about 0 F (540 C) and higher). The annealed condition is normally used for tensile-limited applications (temperatures below about 0 F (540 C)). Tensile Properties INCONEL alloy 601 has high tensile properties at room temperature and retains much of its strength at elevated temperatures. Typical room-temperature tensile properties of annealed material are listed in Table 6.

7 Creep and Rupture Properties INCONEL alloy 601 has good creeprupture strength, and the alloy is widely used for equipment that must withstand extended exposure to high temperatures. The alloy's usefulness for such applications is increased by its resistance to oxidation and other forms of high-temperature corrosion. The rupture strength of solution-treated alloy 601 at various temperatures is illustrated by the Larson-Miller parameter presentation in Figure 5. Creep properties of the alloy at temperatures to 2000 F (90 C) are shown in Figure 6. Rupture life of solution-treated material at various stresses and temperatures is shown in Figure 7.

Microstructure INCONEL alloy 601 is a face-centered-cubic, solid-solution alloy with a high degree of metallurgical stability. Phases normally present in the alloy's microstructure include chromium carbides and titanium nitrides. Figure 8 shows the microstructure of solution-treated hot-finished rod. The large block-like structure visible in the photomicrograph is a particle of titanium nitride. The scattered small particles are chromium carbides. INCONEL alloy 601 has shown complete absence of embrittling intermetallic phases such as sigma. Corrosion Resistance The substantial nickel and chromium contents of INCONEL alloy 601 in conjunction with its content of aluminum give the alloy superior resistance to high temperature corrosion mechanisms. Of particular significance is its resistance to oxidation at temperatures up to 2200 F (1200 C). By virtue of its contents of chromium and aluminum, alloy 601 offers unique resistance to oxide spalling under cyclic thermal conditions. Figure 8.

9 Oxidation INCONEL alloy 601 has exceptional resistance to oxidation at high temperatures. The alloy forms a protective oxide coating that resists scaling even under the severe conditions of cyclic exposure to temperature. Figure 9 compares the performance of INCONEL alloy 601 with the behavior of other oxidation-resistant materials in a cyclic oxidation test at 2000 F (95 C). The specimens were subjected to cycles of exposure to 2000 F(95 C) for 15 min and rapid cooling in air for 5 min. Weight change was determined periodically throughout the test. The resistance of alloy 601 to oxidation at temperatures of 2 F (1150 C) and 2200 F (1200 C) is illustrated in Figures and 11. The data were derived from tests in which the specimens were exposed to temperature for ten consecutive 50-hr periods. After each exposure period, the specimens were cooled to room temperature, brushed lightly to remove loose oxide, and then weighed to determine weight change. The superior oxidation resistance of INCONEL alloy 601 is related to the amounts of nickel, chromium, and aluminum in the alloy. During high-temperature exposure, those elements form an extremely protective and adherent oxide film on the surface of the material. In addition, a slight amount of internal oxidation occurs and provides a higher chromium content in the surface oxide. The protective oxide layer is illustrated in Figures 12 and 13, which are unetched photomicrographs of the cross-sections of specimens exposed to high temperatures.

10 Carburization INCONEL alloy 601 has good resistance to carburization. Tables 13 and 14 give the results of gas carburization tests performed at three different temperatures. The weight-gain measurements indicate the amount of carbon absorbed by the specimens during the exposure periods. Alloy 601 also has good resistance to carbonitriding environments. Table 15 gives the results of tests performed in a gas mixture of 5 ammonia, 2 methane, and 93 hydrogen at 2000 F (95 C). Sulfidation The resistance of INCONEL alloy 601 to sulfidation in an atmosphere of 1.5 hydrogen sulfide and 98.5 hydrogen at temperatures from 1200 to 1400 F ( C) is shown in Figure 14. The weight-loss measurements are for completely descaled specimens after hr of exposure to the environment. +25 Figure 12. Oxide layer on specimen exposed to 2 F (1150 C) for 500 hr. 75X.

Welding products are available which provide performance comparable to that of the base metal in all service environments. Heating and Pickling Like other high-nickel alloys, INCONEL alloy 601 must be clean before it is heated. All foreign substances such as grease, oil, paint, and shop soil must be removed from the material before a heating operation is performed. The alloy must be heated in a low-sulfur atmosphere. Fuels for open heating must be low in sulfur. To prevent excessive oxidation of the material, the furnace atmosphere should also be slightly reducing. INCONEL alloy 601 is not strengthened by heat treatment. Broad ranges of strength and hardness, however, can be achieved with the alloy by the combination of cold work and annealing treatments. The amount of cold work and the section size of the material must be considered in establishing an annealing procedure. Figure 15 shows the effects of annealing temperature on the mechanical properties and grain size of a in. (19- mm) diameter hot-finished rod. The specimens were annealed at the indicated temperatures for 30 min and aircooled before being tested. a Atmosphere consisted of 5 ammonia, 2 methane, and 93 hydrogen. b Average of two tests. 11

12 The effects of annealing temperature on the tensile properties of cold-drawn (45 reduction) wire are shown in Table 20. The finished size of the wire was in. (4.67 mm). The material was annealed at the listed temperatures for 2 min and water-quenched. The rate of cooling after heating has little effect on the mechanical properties of INCONEL alloy 601. However, if the material is to be pickled or exposed to other aggressive environments, it should be cooled rapidly through the F ( C) temperature range to avoid sensitization. Because of its aluminum and chromium contents, INCONEL alloy 601 readily forms a refractory surface oxide during heating and cannot be bright-annealed in the usual industrial furnace. Pickling is normally required to produce bright surfaces on parts that have been heated. Specialized pickling procedures are required for alloy 601 because of its inherent resistance to chemical attack. The light oxide on material that has been annealed and cooled away from contact with air, as in hydrogen, can usually be removed by the nitric/hydrofluoric acid solution described in Table 21. Heavy oxide, such as that resulting from hot-working operations, should be removed with the pickling procedure given in Table 22.

Work-hardening rates for INCONEL alloy 601 and other materials. Hot and Cold Forming The temperature range for hot-forming INCONEL alloy 601 is F ( C). Hot-working operations involving large deformations should be performed at F ( C). The alloy has low ductility at temperatures from 1200 to 1600 F ( C) and should not be worked in that range. Light working at temperatures below 1200 F (650 C) can be done to develop high tensile properties. Table 23 shows the effect of hot-working temperature on the mechanical properties of alloy 601. The material was hot-worked from 6-in. (152- mm) diameter rounds to 4-in. (2-mm) squares and air-cooled. Transverse specimens from the centers of the bars were used for the tests. The rate of cooling following hot-working is not critical with respect to thermal cracking. To avoid sensitization, however, the alloy should be cooled rapidly through the F ( C) temperature range. INCONEL alloy 601 is cold-formed by conventional procedures. The alloy's work-hardening rate, shown in Figure 16, is somewhat higher than the rate for INCONEL alloy 600 and INCOLOY alloy 800. Table 24 gives tensile properties of colddrawn wire after various amounts of cold reduction.

14 Machining All standard machining operations are readily performed on INCONEL alloy 601. For the best machinability, the alloy should be in the solution-treated condition. Additional information on machining can be obtained from the Special Metals publication Machining on the website, Joining INCONEL alloy 601 exhibits good weldability and is readily joined by conventional welding products and processes. Welding products are available which provide high joint efficiencies and heat resistance. The choice of welding product is dependent upon the service conditions to which the fabricated alloy 601 component will be exposed. Table 25 provides general guidelines for welding product selection. Tensile properties of joints in INCONEL alloy 601 welded by the shielded-metal-arc, gas-tungsten-arc, and gas-metal-arc processes are given in Tables 26 through 30.
